Fake Claude App via Bing Ads Delivers SectopRAT Malware
Attackers exploited Bing's ad platform and Anthropic's legitimate Claude.ai domain to distribute a fake Claude desktop installer laced with SectopRAT, a feature-rich remote access trojan with info-stealing and HVNC capabilities. The campaign, dubbed FakeAgent, compromised at least 29 organisations in a 48-hour window by abusing Claude Artifacts as a trusted hosting vector — a novel AI platform abuse technique. The incident highlights how threat actors are weaponising AI brand trust and legitimate AI infrastructure as malware delivery mechanisms.
